pure anatase titania (tio2), mixed 1.0 wt.% cerium-anatase titania (1.0 wt.%ceo2-tio2), and mixed 1.0 wt.% zirconia-anatase titania (1.0 wt.%zro2-tio2) nano powders were synthesized by co-precipitation method and characterized using x-ray diffraction (xrd), brunauer-emmett-teller (bet) surface area analysis, uv-vis diffuse reflectance spectroscopy (drs), and transmission electron microscope (te...

α-Fe2O3 is a stable, cheap, and non-toxic metal oxide with many advantages different fields of application. Many attempts have been devoted to the synthesis crystal structures morphologies obtain desired properties. In this research, nanostructured were synthesized by facile solvothermal route. The as-obtained samples are characterized XRD, FESEM, EDS, FTIR, BET surface area analysis. results s...

agal2o3 nanocomposite were synthesized by solution combustion technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. samples prepared with different amount of silver, were characterized by xrd, bet, sem and optical absorption measurements. xrd analysis was used to determine the change in phase and size of the synthesized nanopar...

We report on a simple technique for the preparation of nanocrystalline metal molybdate Zn1-xCoxMoO4 (0 ? x 1) using polymeric route. The formation mechanism, homogeneity, and structure obtained powders were investigated with thermal analysis (TGA–DTA), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR). morphology was examined by scanning electron microscopy (SEM), f...

in this study, a new adsorbent, silver nanoparticle loaded on activated carbon (ag˗np˗ac) was used for removal of acid yellow199 (ay 199) dye. this novel material was characterized and identified by different techniques such as brunauer, emmett and teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd) analysis. unique properties of this adsorbent such as hig...

This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

In this study, two new Ni/La-Al2O3 catalysts were prepared by a sol-gel method, with different aluminium precursors (aluminium triisopropoxide and aluminium nitrate). The catalysts were characterized by scanning electron microscope (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), BET specific surface area, and particle size analysis (PSA) techniques. The BET results showed that the par...

The present work reports development of a magnetic hydrogel adsorbent material based on the polysaccharide, gum acacia. This graft copolymer nanocomposite acacia and poly(3-chloro-2-hydroxypropylmethacrylate) has been made using microwave assisted technique. Magnetite nanoparticles have generated by in-situ method trapped in network structure. parent hybrid were evaluated as adsorbents for sequ...
